Car-jacking victims have spoken about the horror of being forced from their cars as police warn motorists to keep vehicles locked after three incidents in a day.

One woman was forced out of her car at knifepoint and another dragged from her car and left in the middle of the road.

In the another incident, someone tried to open a man's car door at traffic lights, but failed because it was locked.

Beth Aleksander was the victim threatened with a knife.

Her black Volkswagen Golf was stolen when she was at a red traffic light on Marlborough Road, Manningham, at around 7.45am on Wednesday.

A man got into the car, by the passenger door, and ordered her to get out of it.

When she refused, he threatened her with a knife around the size of a nail file.

“I was just really shocked, Miss Aleksander said.

“He just got into my car and said, ‘just get out of the car, I need the car’.

“I did not get out of the car at first and he said ‘I will **** you up’. He had a knife."

Miss Aleksander climbed out of her car and the man drove it away towards Manningham Lane, on the wrong side of the road, leaving her in the middle of the road.

She said she tried to get her keys out of the vehicle, but the man drove away.

"It just got taken and I’ve got no idea of the reason why," Miss Aleksander, of Idle, said.

“It could have ended a lot worse. It happened really quickly. It only took about a minute.

“I’m more annoyed now than anything, but at the time I was scared. I was really angry."

A laptop and house keys were among items in the car.

The car-jacker was wearing a black hooded top, which was pulled over his face, had fair facial stubble and spoke with a Yorkshire accent.

The Golf, which is still outstanding, has the number plate YK62 JPU.

In another attack, Rebecca Griffin was waiting at traffic lights in her Audi TT in Barkerend Road, at the junction with Killinghall Road, Barkerend.

Three men approached the car, with one man opening the passenger door to steal the 34-year-old's handbag while the others opened the driver's door.

Miss Griffin was told to remove her seatbelt, a struggle followed and one man dragged her out of the car by her arm.

She suffered slight injuries to her elbow, shoulder and collarbone, in the incident, which happened at around 9.45pm.

When the trio spotted an unmarked police car, they ran away with Miss Griffin’s handbag, which contained her mobile phone and cash.

"It was just bizarre. You don’t think it’s going to happen to you. It happened so quick.

“I wasn’t frightened, just shocked," said Miss Griffin, of Eccleshill.

“I just thought at the start how they were not going to get my bag, they were messing with the wrong girl.”

The men were wearing hooded tops, pulled down to cover their faces, and were believed to be Asian.

The attack on Miss Griffin happened around 20 minutes after another incident at the same place.

A man tried to open the driver’s door of a black Seat Leon at traffic lights.

"I feel lucky as I kept my car locked," said the driver, who asked not to be named.

"It was just a horrible experience. There was nowhere for me to go as the driver - there were cars in front and behind me.

"I would say to anyone driving in an inner city to make sure your car doors are locked."

The man was described as Asian, around six foot tall and slim. He was wearing an orange hooded top.

Detective Sergeant Andy Simpson, of Bradford District CID, echoed the warning to drivers.

"These type of incidents are thankfully quite rare in the Bradford district, but they serve as a reminder to motorists to keep their doors locked and windows closed when stationary in traffic," he said.

"Motorists can be vulnerable when sat stationary in traffic, so by keeping your car secure you can prevent opportunist incidents like these."

Police are not currently linking the Manningham incident to the ones in the Killinghall Road area.  

Witnesses should call Bradford District CID on 101, or Crimestoppers, anonymously, on 0800 555111.
